  @section overview Exiv2 Overview

  %Exiv2 comprises of a C++ library and a command line utility to access image
  metadata. %Exiv2 is free software. The homepage of %Exiv2 is at
  <A HREF="http://home.arcor.de/ahuggel/exiv2">http://home.arcor.de/ahuggel/exiv2</A>.

  The %Exiv2 library provides
  - full read and write access to the Exif and Iptc metadata of an image through
    %Exiv2 keys and standard C++ iterators
  - a smart Iptc implementation that does not effect data that programs like
    Photoshop store in the same image segment
  - Exif <A HREF="makernote.html">MakerNote</A> support:
    - %MakerNote tags can be accessed just like any other Exif metadata
    - a sophisticated write algorithm avoids corrupting the %MakerNote:
      <br>&nbsp;&nbsp;1) the %MakerNote is not re-located if possible at all, and
      <br>&nbsp;&nbsp;2) %MakerNote %Ifd offsets are re-calculated if the
                         %MakerNote needs to be moved (for known %Ifd %MakerNotes)
    - new camera make/model specific %MakerNotes can be added to the library with
      minimum effort in OO-fashion (by subclassing %MakerNote or %IfdMakerNote)
  - extract and delete methods for Exif thumbnails (both, Jpeg and Tiff thumbnails)
  - set methods for Exif thumbnails (Jpeg only, Tiff thumbnails can be set from
    individual tags)
  - complete API documentation (by Doxygen)
  - generic lower-level classes to access %Ifd (%Image File Directory) data
    structures

  @section devel Development

  <p>%Exiv2 is maintained in a publicly available subversion repository.
  There is a <a title="Last 50 commits" href="http://dev.robotbattle.com/cmtinfo_svn.php?r=10">
  live list with the latest commits</a> to the repository, and you can
  <a title="Online source code repository" href="http://dev.robotbattle.com/~cvsuser/cgi-bin/ns_viewcvs.cgi/exiv2/trunk/">
  browse the source code</a> online.
  </p>
  <p>To check-out the current source code from the repository, you need a
  <a title="Get Subversion!"
  href="http://subversion.tigris.org/project_packages.html">subversion client</a>.
  If you use a command line client, change to the directory where you want to keep
  the source code and type:</p>

  @verbatim $ svn checkout svn://dev.robotbattle.com/exiv2/trunk . @endverbatim

  <p>To download the test data and test drivers for version 0.9.1 from
  the repository, change to your local exiv2-0.9.1 directory and use the
  following command:
  </p>

  @verbatim $ svn export svn://dev.robotbattle.com/exiv2/tags/0.9.1/test @endverbatim
